FILE OR PORTFOLIO.

SPECIFICATION forming part of Letters Patent No. 448,816, dated March 24, 1891.

Application filed dctober 22, 1890. fierial No. 368,921. (No model.)

To all whom it may concern.-

Be itknown that 1, JOHN J. HANLON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a File or Portfolio, of which the following is a full, clear, and exact description, that will enable others to make and use the same, reference being had to the accompanying drawing, forming a part of this specification.

This invention relates to an improved file or portfolio for the temporary filing of business papers, such as bills, receipts, 850., and is more especially intended for use in the office of railway companies for the convenient filing of papers. Files of this character are frequently referred to and subjected to considerable handling, and it is, therefore, necessary that the structure should be strong and durable and at the same time flexible.

The drawing is a view in perspective of a file embodying my improved features.

Referring to the drawing, A A represent the fly-leaves, and B the different inside or filing leaves. Theleaves composing this bookfile are of thick or heavy stock, so as to form a substantial base or back for the papers filed between the same. The back 0 may be of the flexible character shown or a stiff board back, as circumstances may require. The usual outside covers or binding (not shown) may be secured to the back in any suitable manner. The cloth binding-strips a are attached to the adjacent faces of the different file-leaves and to the flexible back 0, as shown. Considerable space is left between the back edges of the filing-leaves and the backing-strip C, so as to permit of the adjacent surfaces of the respective cloth strips a being joined together over the edge of the file-leaves and thereby afford greater strength and flexibility. The cloth strips to cover a large part of the surface of the leaves, and extend outwardly beyond the point where the temporary fasteners b are inserted in securing the filed paper d in place. Having the cloth binding-strips extend out beyond Where the fasteners are inserted prevents the liability of the leaves being torn in inserting or removing said fasteners.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a file of the character described, the combination of the filing-leaves, the backingstrip providing a space between the adjacent edges of said leaves and back, and the bind ing-strips overlapping the adjacent surfaces of the filing-leaves and joined together between the edge and back and also joined to the backingstrip, substantially as set forth.
